To Wigros Sun, 在iMX6DQ上使用USB TO ETHERNET 芯片同时扩展2个网络口可以吗

[shine_wang]

我们想在iMX6DQ的板子上，USB HOST1 上先用USB-HUB芯片扩展出4个USB口，再用2个USB TO ETHERNET芯片扩展两个网络口，这样可以吗，速度上会有影响吗

Hello Shenghua,

   We have several way to expand ethernet interface:

1. USB port

Just as what you said, USB HOST-->usb hub with 4 ports--> two of 4 ports--> USB to ethernet bridge)-->2 ethernet ports

the way is no problem, if you want speed 10/100Mbps, it is no problem.

2. PCIe port

You can use intel82574 or intel82574it(industrial grade) and connect it to PCIe port.

Above both methods are feasible.

Hope above advice is helpful for you.

Have a nice day!
